Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1052142, here are decompositions:
- 5 + 1052137 = 1052142
- 23 + 1052119 = 1052142
- 31 + 1052111 = 1052142
- 43 + 1052099 = 1052142
- 59 + 1052083 = 1052142
- 79 + 1052063 = 1052142
- 101 + 1052041 = 1052142
- 103 + 1052039 = 1052142
Showing the first eight; more decompositions exist.
